If the Channel is configured for FSK Mode, you can
choose from the following types:
0 – Phase Comparison
1 – Unblocking-2Frequency
2 – DTT-2Frequency
3 - POTT 2-Frequency
4 - 3-Frequency
5 - 4-Frequency
Tx & Rx Frequency
<tx_freq>250.35</tx_freq>
<rx_freq>252.55</rx_freq>
These are the transmit and the receive frequencies
within the range of 30 to 530 kHz in steps of 0.01
kHz, e.g. 250.55 is 250.55 kHz.
Bandwidth and Shift
Bandwidth & shift is specified as a single digit
number:
ON/OFF Mode
<bandwidth>1</bandwidth>
1 – Sets the bandwidth to 600 Hz.
2 – Sets the bandwidth to 1200 Hz.
3 – Sets the bandwidth to 4000 Hz.
FSK Mode
<txbwshift mode="FSK">2</txbwshift>
<rxbwshift mode="FSK">2</rxbwshift>
This is called the TX Bandwidth-Shift & RX
Bandwidth-Shift
0 – Sets the bandwidth-shift to 300±100 Hz.
1 – Sets the bandwidth-shift to 600±100 Hz.
2 – Sets the bandwidth-shift to 600±250 Hz.
3 – Sets the bandwidth-shift to 1200±250 Hz.
4 – Sets the bandwidth-shift to 1200±500 Hz.
FSK - 3 & 4-Frequency has only
0 – Sets the bandwidth-shift to 600±250 Hz.
1 – Sets the bandwidth-shift to 1200±500 Hz.
Tx Power
<tx_low>1.5</tx_low>
<tx_hi>9.5</tx_hi>

appendix C: Xml File Format
The tx_hi and tx_low values must be between 1 &
10 W in steps of 0.1 W, with tx_low smaller than
tx_hi, e.g. 1.5 specifies 1.5 W.
Fade Alarm
<fade_alarm>10</fade_alarm>
Fade Alarm is between 1 & 25 dB
Fade Margin
<fade_margin>15</fade_margin>
Fade Margin is between 1 & 25 dB
Reflected Power
<reflpwr>15</reflpwr>
Reflected power is 1 to 100% in 1% increments
Shift Up to Trip
<shift_up_to_trip_tx>0</shift_up_to_trip_tx>
0–sets the transmitter to see a shift down to trip sig-
nal
1–sets the transmitter to see a shift up to trip signal
<shift_up_to_trip_rx>0</shift_up_to_trip_rx>
0–sets the receiver to see a shift down to trip signal
1–sets the receiver to see a shift up to trip signal
Transmit/Receive Enable
<tx_rx_enable>3</tx_rx_enable
3–Both transmitter and receiver enabled
2–Receive only (transmitter is disabled)
1-Transmit only (receiver is disabled)
Logic Settings
Voice
<voice>2</voice>
Voice is a single digit value. Only 1 or 2 is valid:
1 – Beep Disabled
2 – Beep Enabled
Pre-trip Delay (Valid for FSK Mode Only)
<ptt_delay>30</ptt_delay>
Pre-trip Delay is 0 – 30 ms in 1 ms steps.
Trip Hold (Valid for FSK Mode Only)
